Reaction Steps

The general method of procedure B was followed with cyclopentanesulfonamide (7.45 g), sodium methoxide (2.7 g), methanol (200 ml), tetrahydrofuran (200 ml), and 4-fluorophenyl isocyanate (6.85 g). The residue was dissolved in water and the solution acidified with 1N HCl. The resulting solid was separated and recrystallized from benzene to give 2.9 g of white solid with a melting point of 155°-157° C.
